Great Merchant is a 2D fantasy MMORPG set in East Asia. The game emphasizes trade and encompasses many cities across China, Korea, and Japan. Players chose from 8 characters and must build a fortune by fighting NPCs, investing in cities, and participating in commerce.

Great Merchant is a trade oriented MMORPG with an interesting combat system. Play as one of eight character looking to make it in the world of commerce and jump into a 2D rendition of the ancient far east. The graphic style in Great Merchant is similar to that in Luminary: Rise of the Goonzu and the two share other features as well. Players can visit hundreds of towns, invest in them and buy/sell/craft items at various markets. Combat is handled on a separate screen after players engage with NPCs on the main map. Players can hire mercenaries or monster pets to assist them in combat, both the main character and allies level up and earn stat points which can be distributed among 4 stats: Strength, Agility, Vitality, and Wisdom.
